Need a small customization of jomsocial

i have got a joomla site with jomsocial installed. Jomsocial is a comunity component for joomla, you can find here: [url removed, login to view]

Now the problem. If a user edit his profile details (and i have got a few profile fields - mandatory and not mandatory) and for example he forgot to fill out a mandatory field and click on save, an error message appears, that he has forgot to fill out this field. That is ok, but than all changes or new entries in the whole fields are gone and he has to fill out everything (and not only the field he has forgotton) again! And that is really terrible for the users. So, if a user fills out a field, it must be saved automatically in a cookie or db, so if he makes a mistake and click on save, the error message appears, but everything he has filled out before (also the new changes he has done) must be still there and not deleted, so he only has to fill out the missing field to go on.

I need this fix urgent. It must be possible to start today and finish also today.

Best regards,

Noelle

Sorry, i forgot to edit the price for this work. So it should be more cheaper than 250$ ;-)
